New photos of the Earth A brown ash banner emerges from space, which rises on Saturday (June 22) after an eruption from the Raikoke volcano in the North Pacific.
One of the pictures was taken by an expedition astronaut 59 at the International Space Station on the morning of the outbreak. The largely dormant volcano erupted for the first time in nearly 100 years at 4 o'clock local time (18 o'clock GMT on 21 June) and sent a cloud of thick volcanic clouds 8 to 10 miles (13 to 17 kilometers) above the sea level to the European Space Agency, whose Copernicus Sentinel satellite was the outbreak of orbit.
The picture also shows a cloud ring at the base, which appears to have formed from water vapor, NASA officials said in a statement. NASA's Terra and Suomi nuclear power satellites also saw the cloud in space.

"What a spectacular picture," said Simon Carn, a volcanologist at Michigan Tech, in the NASA statement. "The ring of white, swollen clouds at the foot of the pillar could be a sign that ambient air is being sucked into the column and water vapor is condensing, or it could be an ascending cloud of magma-seawater interaction, since Raikoke is small The island and rivers are likely to have entered the water. "
Raikoke is one of the Russian Kuril Islands and has erupted twice – in 1778 and 1924.
The recent eruption was a surprise, and satellites have tracked down the ashes the volcano, as it can pose a threat to aircraft, according to NASA.
The satellites also tracked the movement of volcanic gases – Raikoke produced a concentrated sulfur dioxide plume that moved east as she headed for a storm in the North Pacific.
Carn pointed out that the toxic gas could have reached the stratosphere, the second layer of the atmosphere. "The persistence of large quantities of SO2 in the last two days also indicates a stratospheric injection," he said in the statement.
